Odd problem with a new PC. I purchased a Mach Speed P4MST-890 Socket 775 Motherboard with a Intel Pentium D 925 3Ghz DT 800FSB Socket 775. I am using the ZEROtherm CPU Cooler CF900 775 as a cooler and my case is a Power Up Silver 5511 ATX Mid-T Case w/450w PSU.
The problem I am running into is, if I try and stand the case up so it is standing normally, it shuts off after a few minutes. But if I lay it on its side, it runs with no issues. What am I missing here?
